先加入個NotifyIcon控制項，程式如下：

private void button1_Click(object sender, EventArgs e)
        {
            this.notifyIcon1.Visible = true;  //啟用notifyicon
            this.notifyIcon1.ShowBalloonTip(1000, "標題", "123123123", ToolTipIcon.Error); 
        }

        private void button2_Click(object sender, EventArgs e)
        {
            this.notifyIcon1.Visible = false;  //停止notifyicon
        }
